Diamond Mosaic Kitchen Backsplash in Blue Island
About This Project
A kitchen bar area in a Blue Island home with sage green painted cabinetry and a white quartz countertop — the homeowner wanted a backsplash that added texture without competing with the cabinet color. The choice was a white diamond-pattern mosaic tile set on mesh backing.
Mosaic tile on mesh backing requires a different trowel notch than large tile — we used a 3/16-inch V-notch trowel to get full coverage without the thinset squeezing up through the mesh joints. The diamond pattern also required centering the layout carefully so the point of a diamond landed at the center of the countertop run rather than a grout line. That's a dry layout decision we make before any thinset goes on the wall.
The outlets in this Blue Island kitchen were recessed slightly behind the original tile, which we addressed by adding tile depth extensions to the boxes so the new cover plates would sit flush. A detail most homeowners don't think about until the tile is already up.
What We Did
- Remove existing backsplash tile, check drywall condition and outlet box depths
- Dry layout of diamond mosaic to center pattern on countertop run
- Set mesh-backed mosaic with white thinset, 3/16-inch V-notch trowel
- White unsanded grout, caulk at countertop-to-tile joint
